摘要： A chirped pulse amplification laser system. The system generally comprises a laser source, a pulse modification apparatus including first and second pulse modification elements separated by a separation distance, a positioning element, a measurement device, and a feedback controller. The laser source is operable to generate a laser pulse and the pulse modification apparatus operable to modify at least a portion of the laser pulse. The positioning element is operable to reposition at least a portion of the pulse modification apparatus to vary the separation distance. The measurement device is operable to measure the carrier envelope phase of the generated laser pulse and the feedback controller is operable to control the positioning element based on the measured carrier envelope phase to vary the separation distance of the pulse modification elements and control the carrier envelope phase of laser pulses generated by the laser source.

摘要： A laser and amplifier combination delivers a sequence of optical pulses. Pulses from the laser are temporally stretched by a pulse stretcher before amplification and temporally compressed by a pulse compressed after amplification. The pulse stretcher includes a diffraction grating on which pulses being compressed are incident. An arrangement is provided for measuring the carrier-envelope phase of the pulses and adjusting the incidence angle of pulses on the grating cooperative with the measurement such that the carrier envelope phase of the pulses in the sequence is about constant.

摘要： A laser and amplifier combination delivers a sequence of optical pulses at a predetermined pulse-repetition frequency PRF. An interferometer generates a signal representative of the carrier-envelope phase (CEP) of the pulses at intervals corresponding to the PRF. The signal includes frequency components from DC to the PRF. The signal is divided into high and low frequency ranges. The high and low frequency ranges are sent to independent high frequency and low frequency control electronics, which drive respectively a high-frequency CEP controller and a low frequency controller for stabilizing the CEP of pulses in the sequence.
